DRY CLOSET.

Application lled February 3, 1917.

To all whom t may concern:

Be it Vknown that I, FRANK PAVLIK, Jr., a citizen of the United States, residing at Westminster, in the county of Adams and State of Colorado, have invented certain new and useful Improvements in Dry Closets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to maire and use the same.

This `invention relates to improvements in dry closets of that type particularly known to the trade as sanitary indoor chemical closets.

Gutside privfies being extremely inconvenient and undesirable, tlie chemical type of indoor closet is primarily designed for use on the farm, homestead or other outlying localities, where the facilities of city sewerage are not available and hence the usual Water flushing closets are not feasible for installation.

Their` object, therefore, is to provide a dry closet for use indoors, which is effectively odonless and substantially sanitary and in these respects unobjectionable.

In the accomplishment of these aims, there is employed .a portable container, char ed with a liquid mixture containing a suitable chemical of a non-combustible and substantiall non-poisonous nature, but which has siniicient strength to function as a germicidal decom oser and deodorizer to throw down or destroy the acids, stench and Apoisonous gases arising from the fecal and urine contents of vsaid container.

These closets, as `heretofore constructed and installed, provide a main receptacle associated in a fixed and non-displaceable relation with a vent pipe, and within the main receptacle is inserted a portable can or container for the excrement matter, but in many respects they have proven more or less objectionable and unsatisfactory in practical use, for reasons which will hereinafter appear.

My main object is to improve conditions fby providing a durable and effective closet of a unitary tportable form to decrease the Specrication of Letters Patent.

cost of manufacture, and which may be installed by the purchasers themselves, with comparatively little trouble and expense, an end especially desirable in sparsely settled places.

With this primary aim in view, my specific invention resides in the particular construction and combined arrangement of parts as hereinafter fully described, the special features of novelty being more succinctly stated in the appended claim.

To more fully understand the invention, reference is had to the accompanyi drawings, forming a part of this application and illustrating a practical embodiment of the improvements, in which drawings like parts are designated by the same reference numerals throughout the several views, of Which- Figure 1, is a front elevational view.

Fig. Q, is a central vertical sectional view of the detachably installed closet, looking in the direction of the arrow 2 of Fig. l.

Fig. 3, is an .elevational View looking at ,the rear of Fig. 4 as indicated by the arrow 3.

i? ig. 4, is a fragmentary side elevational view, ,showing a detachable hinge support for the seat, the container receptacle being shown in dotted lilies, and

Fig. 5, is a detail view, partly in section, illustrating a slightly modified connection between the container receptacle and vent pipe standard.

1 designates a vent pipe, leading from the Vrifiniture Ato Vthe atmosphere, ypreferably terminating above the ridge pole of the lbuilding, and to the lower end of `this vent pipe is telescoped a hollow pipe support 2 fixedly secured in place, as to the Wall or floor of a room, in any suitable way, shown in the drawings as comprising a hollow standard with its base 3 bolted to the door, and providing a vent chamber, closed at its lower end to the atmosphere, and at its upper end communicating with said vent pipe l.

This hollow support 2 has a lateral hollow extension 4, opening into said vent chamber, and imniovably fixed relatively to said hollow standard 2 and the vent pipe 1, which lateral extension flares outwardly as an open cone, and this cono formation has its important function as will later apiear.

The detachable and portable unitary container receptacle itself is indicated at 5. having a hand grip on its lower forward periphery, and a bail 7 secured to the side ears S as usual` the bail. being of sullicient radius to swing over the seat and rest on the extension et, out of the way, as showvn at Fig. 2.

Near the upper open end of the receptacle, its peripheral Wall is apcrtured and provided with a tubular continuation or extension 9, preferably of cylindrical form. The height of the extensions l and 9, relative to each other. is such that these extensions are disposed in axial alinement, the diameter of the extension 9 being substantially less than the Haring base portion of the cone 4 but greater than the apex portion thereof.

l() designates the usual apertured toilet seat, having the lid il hinged thereto at l2, and this seat is in turn hinged in a detachably supported manner to the lop of the receptacle 5 by the novel means of a bent over clip fastener element 13, of a curvature to snugly envelop the top rear edge of the receptacle. The rear spaced Wall of this fastener clip 13 is scored With a pair of slits and bent back upon itself to form the hinge knuckle l5, associated With similar hinge elements 14 carried by the seat, and pivotally connected together by the usual hinge pin.

It is obvious that, in some cases it may be expedient to slightly bevel the end of the tube J of Fig. 2 to provide a cone-tipped. seat, or to attach a rubber or similar gasket, cone-shaped or otherwise, to make the joint tighter, and in Fig. 5, I have shown a gasket simply in the form of a ring 2() seated in a recess on the end of the tube. Also a lug la may be disposed on the eXtension 4, as shown in this figure, behind Which the hail projects in substantially latched relation.

In installing my fixture, the hollow fixed support Q is suitably secured in place, as stated, with its upper end opening into the vent pipe l, and the conical extension i disposed forwardly at a position above the floor to properly receive the tubular extension 9 in readily detachable relation, but at the same time making a tight or non-leak joint.

By this improved style of detachable connection, when the receptacle 5 has been Withdrawn, using the hand grip (i, to be carried away and emptied, it may be readily replaced by shoving it into position again without the annoyance of adjustment, as owing to the cone formation of the extension l, the tube 9 will be positively guided into perfect seating relation with the inner Wall of the cone, effecting a tight joint, and When the lug l is employed, as shown in Fig. 5, the engagement of the bail behind the lug will, if necessary, provide a substantial means to assist in preventing displacement of the receptacle and connecting parts. Also, by the conical connection, a slight side- Wise movement of the receptacle, in attaching or detaching same, will not displace the fixed parts, as might be the case With cylindrical tubes, which are hard to telescope.

From Fig. 2, it is evident that the closet may be used as a stool or urinal, and where a new container is to replace the illed one, while the latter is being emptied, cleaned and aired or otherwise, the Whole seat may be easily removed and replaced by means of the detachable clip fastener element 13 heretofore mentioned.

Thus it Will be seen that, With a detachably associated `receptacle of unitary structure, I accomplish With greater efficiency what has heretofore been done with a more complex and unsanitary fixture requiring a fixed outer receptacle and a removable 1nner container, and outside of decreasing the much higher cost of manufacture and the consequent large saving to the purchaser, my improved unitary structure has many other advantages, including a more sanitary closet, of increased capacity for the same space required, there being no inner container and outer receptacle, as heretofore, whereby the soil and urine formerly slopped over the inner receptacle into the outer one, a very objectionable feature as to cleanliness and sanitation, as will be obvious.

In my improved closet, a suitable chemical mixed in liquid form is also employed, and the noxious odors and gases, not entirely killed by the chemical, are carried away, as indicated by the arrows of Fig. 2, out through the connections 9 and 4 and the vent pipe 1.

lVhile I have thus fully described my invention, and While the same resides in the novel construction and combined arrangement of parts as disclosed, still it will be understood that I do not limit myself to the exact details as set forth, excepting as come within the purview of the ensuing claim and a reasonable construction of the scope thereof contemplating a fair range of equivalents.
